Dean Koontz said this quote

You are reformed, you may be a better man, but you are not a different man. How can you convince yourself of such a thing when you are so conversant with the theology of your faith? From one end of this life to the other, you carry with you all that you have done. Absolution grants you forgiveness for it, but does not expunge the past. The man you were still lives within you, repressed by the man you have struggled to become.
